Sure we feel better, but they're not going to suck. Every position has an affect on the other. Part of Bortles looking amazing was his WR corps... UCF returns basically all of them. One single guy (Hoffman) made Heaps and Nelson look better because he just caught everything and made big time plays. UCF has a bunch of good receivers. And their RB that will take over for Johnson is a good back. As the full time man, he could end up even better than Johnson.
I don't agree that it will be the hardest game, but it will be hard for sure. If they have a QB that's even half decent they'll be dangerous.
